In case you have implemented Identity Management and see a callback error in the console during the login or logout of users, you will need to add your website's URL to the list of Authorized Javascript Origins in the Identity Management configuration under Edit Business:
An example of such a GET request with a 403 error can be found below:
https://sandbox.tinypass.com/id/api/v1/identity/token/verify?callback=jQuery112405892386686107727_1605862397049&client_id=iXOsFtXlsu&token=&site=https%3A%2F%2Fpiano.io&_=1605862397051 net::ERR_ABORTED 403
Please note, that this error doesn't affect any login or logout functionality.
